Description

TECHNICAL FIELD The present invention relates to a grain conveying device adapted to elevate grains to be processed in a threshing section to, for example, a sorting mechanism, a handling room, a grain tank, or the like. 2. Description of the Related Art In such a grain transporting device, there is a grain transporting device in which a part of a conveyor tube is removed to inspect and clean the inside of the conveyor.

[Problems to be solved by the invention] Conventionally, Japanese Utility Model Laid-Open No. 57-104860 and Japanese Utility Model Laid-Open No. 58-53534
There were techniques disclosed in Japanese Patent Laid-Open No. 52-50864 and Japanese Patent Laid-Open No. 50-50864.

However, the technique disclosed in Japanese Utility Model Laid-Open No. 57-104860 is such that the frying tube is formed in two pieces in order to make the middle part of the frying tube into a large diameter. It is a structure that allows it to enter the inside of the grain tank, not a structure that allows the fried cylinder to be easily opened.

Further, the technology of Japanese Utility Model Publication No. 58-53534 discloses that a cleaning lid is provided on the lower part of the conveyor tube, and the conveyor tube is used as a structure for supporting the upper end insertion body. It is not a structure that can be formed large over the entire area.

Further, the technology of JP-A-52-50864 is a structure in which a second reducing screw conveyor and a conveyor tube are provided inside the threshing section, and a base end feeding case section, an upper end charging body, and a conveyor tube are separately formed. There is no description suggesting any of the above.

In short, each of the above-mentioned conventional techniques does not fix the base end feeding case part, the upper end throwing body, and the fixed body of the conveyor cylinder to the outer surface of the threshing unit, and the conveyor cylinder is formed by dividing the conveyor cylinder in the longitudinal direction. Since the body is not freely attached to the fixed body, there is a problem that inspection and cleaning of the second reduction screw conveyor is extremely troublesome.

"Means for Solving the Problem" Therefore, the present invention is, below the sorting mechanism at the lower part of the threshing section, a proximal end sending case connected to the feeding end section of the second conveyor for collecting the second processed product, and the threshing section. It is equipped with an upper-end thrower that is attached to the No. 2 processed product return section, and a No. 2 reduction screw conveyor that conveys the No. 2 processed product from the base end delivery case section to the upper-end thrower. The conveyor tube to be inserted is divided into a fixed body and a movable body in the longitudinal direction, and the fixed body is fixed between the case portion and the upper end throwing body at the outside of the threshing section, and the movable body is attached to this fixed body. It is characterized by being attached so that it can be opened freely.

"Working" Therefore, since the entire area in the longitudinal direction of the conveyor cylinder is opened by the operation of the movable body, it is possible to easily inspect and clean the entire No. 2 reduction screw conveyor, and at the lower part of the threshing section below the sorting mechanism. Since the fixed body is connected between the base end feeding case part to be disposed and the upper end charging body, the structure of supporting the second reducing screw conveyor by the case part and the charging body is simplified, and the fixing body and the second reducing screw are arranged. It is possible to easily secure the support strength of the conveyor, and for example, in the conventional structure in which a cleaning lid that opens and closes a part of the conveyor cylinder is provided, if the cleaning lid is small, inspection and cleaning of the second reduction screw conveyor is troublesome and If a large cleaning lid is formed, there is a problem that the strength of the conveyor cylinder is reduced. However, these problems can be solved, and a structure for incorporating a No. 2 reduction screw conveyor is provided. Resulting achieving such simplification and improvement in strength of the body mounting structure facilitates, also those obtained achieving such improvement, such as handling ease assembly easier.
